This invention relates to improvements in drawing frames, roving frames,and like textile frames as commonly used in the treatment of bastfibres, e. g., fibres of jute, flax or hemp, and has 5 for an object toprovide an improved mounting of the slip rollers or retaining pressingrollers in such a frame.

In existing constructions the slip rollers are usually closely fitted inrows in end to end relation so that they may be in correct alignment, itmay be with the interposition of distance pieces of the same diameterwhere this is required to suit the pitch of gill in use. These rollersare relatively heavy, and the operative is liable to have his or herfingers nipped when manipulating such rollers in the event of a sliverrunning out and requiring to be replaced by a fresh sliver.

In the improved construction according to the present invention the sliprollers are so mounted that they may be more conveniently raised andremoved when required.

According to the invention, in a drawing, roving or like textile frame,there is provided, for lifting each slip roller, a lever presenting alaterally projecting pin which enters with substantial clearance anaxial bore in the slip roller, the arrangement being such that the sliproller is normally free to co-operate with the associated retainingrollers but is lifted clear of the retaining rollers when the lever isrocked in the appropriate direction.

The invention is illustrated, by way of example, in the accompanyingdrawing in which Fig. 1 is a part elevation part vertical section andFig. 2 is a plan view, showing parts of a textile frame and a preferredconstruction of the slip roller lifting means.

As shown, I denotes the usual fixed rod carrying sliver guide brackets2. Secured in spaced relation on the rod 1 are stop brackets, such asindicated at 3, each presenting an angularly spaced pair of stops 3 and3 Pivotally mounted on the rod 1 are pairs of levers 4, the levers ofeach pair being spaced apart on the rod I by a stop bracket 45 3. Eachlever 4 carries a laterally projecting pin 5 which enters withsubstantial clearance an axial bore 6 in a slip roller 1, so that, inthe normal or lowered position of the lever 4, the

roller 1 is free to co-operate with the retaining rollers 9 and I0.When, however, the lever is rocked in the direction indicated by thearrow A in Fig. 1 by manipulation of a handle or extension 4 integraltherewith, the respective slip roller 6 is lifted away from theretaining rollers 9, l and is held in its limiting raised position shownin dotted lines in Fig. 1. Provided on each lever 4 is a snug 8 which,when the lever is in normal or lowered position as shown in full linesin Fig. 1, with the slip roller 1 free to co-operate with the rollers 9,I0, engages the respective stop 3 and so holds the lever in loweredposition with the pin thereon clear of the peripheral wall of the bore6. In the limiting raised position of the lever 4 the snug 8 engages thestop 3 so that the lever with the slip roller is held inraised position,in which latter position the slip roller can be readily slipped off thepin 5, and any lap around the roller can be unrolled or cut off.Further, a fresh sliver may be rapidly and readily introduced in theraised position of the slip roller.

I claim:--

1. In a drawing, roving or like textile frame, in combination withretaining rollers, slip rollers co-operating with said retainingrollers, each slip roller formed with an axial bore, a lever for liftingeach of said slip rollers, said lever presenting a laterally projectingpin which enters with sub,- stantial clearance the axial bore in therespective slip roller, said slip roller being normally free toco-operate with the associated retaining rollers but adapted to belifted clear of said retaining rollers on rocking movement of saidlever.

2. In a drawing, roving or like textile frame, the combination recitedin claim 1 in which the permissible angular movement of each lever islimited by a pair of stops one of which serves to sustain the lever inlowered position and the other of which serves to sustain the lever inraised position.

3. In a drawing, roving or like textile frame, the combination recitedin claim 1 in which the levers are pivotally mounted on the rod whichcarries the sliver guide brackets of the frame,

said rod also carrying stop brackets presenting spaced stops engageableby snugs on the levers. GORDON SCOTT FRASER.
